We report on the formation of translationally cold Cs[sub 2] ground-state molecules through photoassociation of laser-cooled cesium atoms in a magneto-optical trap. The cold molecules are obtained after spontaneous decay of photoassociated molecules, and detected after pulsed-laser photoionization into Cs[sub 2][sup +] ions. Photoassociation spectra of cesium attractive molecular states below the 6S[sub 1/2]+6P[sub 3/2] dissociation limits are reported, obtained with both ion detection and trap-loss method. A temperature as low as 20[sub -5][sup +15] has been measured for the molecular cloud. © 2000 American Institute of Physics.

    There is a well-known correlation between the shape of the relaxation function (nonexponentiality) and the temperature-dependence of the relaxation times (e.g., fragility), with broader relaxations associated with steeper T[sub g]-normalized temperature dependences. Herein, exceptions to this...

    The possibility of achieving the high density of negative hydrogen ions N[sup H-] in a low-voltage cesium-hydrogen discharge is investigated. The N[sup H-] density is determined experimentally from the absorption of laser radiation due to the photodetachment of electrons from H[sup -] ions. The...

    In a magnetic field, Cs2 molecules were excited from the ground X1Σ+g(vX=0,JX=55) level to the D 1Σ+u(v=46,J=54) level by dissociation laser light linearly polarized parallel to the field, for which the magnetic sublevels were degenerated and thus all the transitions between them were...

    Abstract. A femtosecond UV laser pulse is used to resonantly excite CsCl molecules from the ionically bound ground state to the first excited repulsive state. The excitation leads to the dissociation of CsC1. Alter a certain time delay a visible (VIS) femtosecond laser pulse interrupts the...
